went to the track last night and was very disappointed with my time.
R/T... .335
60'... 2.353
330... 6.489
1/8... 9.848
MPH... 72.58
1000...12.832
1/4... 15.370
MPH... 89.35

mods are:
pacesetters
CAI
cat back exhaust
E-fan
160* T-stat
4:10s with Truetrac
dyno tune

it was about 60*-65* last night so i don't think it was because of the temp.
I ran the same time with just a CAI and cat back exhaust.
and why are my 60' so shitty? it was not spinning?

 

its got to be in the tune? , or the DA was scary high, even though you have good temps the air could of been shitty, what track was this at? and times you ran, I can look it up for ya.

 

I went 15.1 in an ecsb with tune, headers, y pipe, no cats, intake,exhaust and 3.42 open diff. The air had to be crappy or your tune needs adjusting.I am also a 4.8.

 

i was at MIR, there were cars there beaking track records last night.

 

My 60 foot was 2.351 with the 3.42s,open diff, and the extra weight of the extended cab. It has to be the tune. Sometimes a dyno tune is not as good as a street tune. You got any torque management removed.

 

That's not too bad really. A stall and some DR's would get you down a good bit. The stock converter sucks when its behind a 4.8.

 

With bolt ons and cam I didn't run a whole lot better. Converter will get the short time down.

 

i had some torque management removed, but what pisses me off is the fact that it ran the same time with a CAI and exhaust

 

You only ran once though? Could of been some poor gasoline?

 

get that 60 down its killing you and i think the mph should be a little higher also
